Note
The UltraPort fan-out cables need to be secured or supported in case of sudden contact or excessive weight on the cables. Please ensure that adequate caution is taken to avoid possible damage to the UltraPort card or Host system. This can be accomplished by securing the cables to a rack or to the back of the server.
